Method and Apparatus for Frequency Filtering Using an Elastic, Fluid-Filled Cylinder

Abstract

A method and system are provided for frequency filtering compressional wave energy. An elastic cylinder is filled with a fluid that is selected based on a fluid density p and a dilatational wave phase velocity ci thereof. When the elastic cylinder so-filled is subjected to a compressional wave propagating in a fluid environment, a first radial resonance frequency of the elastic cylinder is controlled by the fluid density p and the dilatational wave phase velocity ci. Further tuning of the first radial resonance frequency can be achieved by adjusting the radial wall thickness of the elastic cylinder.
